DTC Descriptors
DTC P0658
- Solenoid High Control Circuit Group 1 Low Voltage
DTC P0659
- Solenoid High Control Circuit Group 1 High Voltage
Circuit/System Description
The transmission control module (TCM) high side driver 1 is located inside of the control solenoid valve assembly, which has no serviceable components. The high side driver 1 provides power to the pressure control solenoids and shift solenoids. This fault is handled inside the TCM and no external circuits are involved.
Conditions for Running the DTC
P0658
* High side driver 1 is enabled.
* DTC P0658 is not set.
P0659
DTC P0659 is not set.
Conditions for Setting the DTC
P0658
TCM detects an internal open or short to ground in the high side driver 1 circuit for 1 second.
P0659
During TCM power-up and prior to the high side driver being enabled, the TCM detects an internal short to voltage on the high side driver 1 circuit a total of 3 times out of 5 consecutive readings.
Action Taken When the DTC Sets
P0658
* DTC P0658 is a Type A DTC.
* TCM turns the high side driver OFF.
* TCM turns OFF all solenoids.
* TCM commands maximum line pressure.
* TCM freezes transmission adaptive functions.
* TCM commands the torque converter clutch (TCC) OFF.
* TCM inhibits Tap Up/Down function.
* TCM inhibits manual shifting of forward gears.
* TCM limits the transmission to Reverse and 5th gear operation.
* TCM inhibits neutral idle.
P0659
DTC P0659 is a Type C DTC.
Conditions for Clearing the DTC
* DTC P0658 is a Type A DTC.
* DTC P0659 is a Type C DTC.

Circuit/System Verification
1. Ignition ON, verify with a scan tool the High Side Driver 1 parameter displays On or Enabled.
• If the High Side Driver 1 parameter displays OFF
Refer to Circuit/System testing below.
• If the High Side Driver 1 parameter displays ON or Enabled
2. Engine Running, gear selector lever in Park position. Verify with a scan tool the following test status parameters display OK:
* High Side Drvr. 1 Ckt. Low Voltage Test Status
* High Side Drvr. 1 Ckt. Open Test Status
* High Side Drvr. 1 Ckt. High Voltage Test Status
• If any test status parameter displays Fault or Malfunction
Refer to Circuit/System Testing below.
• If all test status parameters display OK
3. After performing the above steps, verify that the DTC does not reset by operating the vehicle within the Conditions for Running the DTC. You may also operate the vehicle within the conditions you observe from the Freeze Frame/Failure Records data. If the vehicle passes the Circuit/System Verification procedure, then STOP. Do not perform the Circuit/System Testing or Component Testing as this may result in an unnecessary part replacement. Refer to Testing for Intermittent Conditions and Poor Connections Testing for Intermittent Conditions and Poor Connections.
Circuit/System Testing
Note: You must perform the Circuit/System Verification first.
1. Ignition OFF, remove the Q8 control solenoid valve assembly. Refer to Control Solenoid Valve and Transmission Control Module Assembly Replacement Service and Repair.
2. Perform the Control Solenoid Valve and Transmission Control Module Assembly Inspection Control Solenoid Valve and Transmission Control Module Assembly Inspection. The Q8 control solenoid valve and transmission control module assembly must be externally cleaned of all debris.
3. Place the Q8 control solenoid valve assembly on a clean work surface near the transmission assembly.
4. Connect the DT-47825-20 - adapter harness between the vehicle wire harness X1 20-way transmission electrical connector, and the Q8 control solenoid valve assembly electrical connector.
5. Ignition ON, verify with a scan tool the following test status parameters display OK:
* High Side Drvr. 1 Ckt. Low Voltage Test Status
* High Side Drvr. 1 Ckt. Open Test Status
* High Side Drvr. 1 Ckt. High Voltage Test Status
• If any test status parameter displays Fault or Malfunction
• If all test status parameters display OK
6. All OK.
Repair Instructions
Note:
* Perform the Reset Transmission Adapts Reset Transmission Adapts following all transmission related repairs.
* Before replacing the TCM, perform the Control Solenoid Valve and Transmission Control Module Assembly Inspection Control Solenoid Valve and Transmission Control Module Assembly Inspection.
Perform the Diagnostic Repair Verification Verification Tests after completing the diagnostic procedure.
